I'm building a wordpress website http://salafiwales.co.uk

On the blog I don't mind all the info, date, time, comments etc on the page but on my " in store " page I have items posted and I do not want all the info on ech page. I have put the following css to get rid of it all: However I want to place all the post id's for the items for the same rules ie postid-386 etc so how do I do this without creating rules for each class?

.postid-374 #sidebar {
display: none;
}
.postid-374 #content {
background: none;
}

.postid-374 #category-name {
display: none;
}

.postid-374 #reply-title {
display: none;
}

.postid-374 #comment {
display: none;
}

.postid-374 .form-allowed-tags {
display: none;
}

.postid-374 .form-submit {
display: none;
}


.postid-374 #comment {
display: none;
}
